Is the ventricle lumen larger during systole, Biology

Assignment Help:

Is the ventricle lumen larger during systole or during diastole?

Systole is the stage of the cardiac cycle on which the ventricles contract. So the lumen of these chambers is decreased and the pressure upon the blood within them is heightened.

During diastole the opposite happens. The muscle fibers of the ventricles relax and the lumen of these chambers enlarges helping the entrance of blood.
